Though the human body
depends on water to survive, many people don't drink enough of it.
Dr. David Dupree, a board-certified general surgeon in New York, says
water makes up about 60 percent of your body weight. Every part of your
body depends upon water to function properly.
"Think of it really as the fountain of youth," Dupree said. "It's the
most basic thing, yet it runs the most complicated machine, our bodies.
So, we're going to consume a lot. We have to maintain the machine to
keep it moving."
However, your body expels water through everyday bodily functions, such
as breathing and sweating. Conventional wisdom says to drink at least
eight glasses of water per day, but that figure isn't actually based on
solid scientific evidence.
Doctors say everyone's body is different. Dupree said, ""I think
everybody has a different view on how much. Usually, the standard has
been eight glasses of eight ounces of water a day. That allows us to
sort of maintain our function."
The amount of water you should drink depends on many factors such as
weight, gender, activity level and age. The National Academies of

most men is about 15.5 cups. Women typically need 11.5 cups per day.
If you're not a big water drinker, nutritionists report that certain
fruits and vegetables, such as watermelon, spinach and cucumbers, can
